Definitions

  • the present invention relates to a method and apparatus of polishing end surfaces of rod-shaped members, which is suitable for polishing the respective end surfaces of a plurality of rod-shaped members at the same time, as per the preamble of claims 1 and 2.
  • An example of such apparatus and method is disclosed by US 5 184 433 A.
  • end surfaces of rod-shaped members such as ferrules with optical fibres are required to be finished into a desired shape by polishing the end surfaces
  • a large number of ferrules 102 with optical fibres are fixed to a periphery 101 of a regular polygonal holder 100 by suitable means while leaving a space between the ferrules, and a relative trochoid curvilinear motion is caused in the state that the respective tip ends of the ferrules 102 with optical fibres are pressed against a polishing disc 103 disposed opposite the holder 100, whereby the respective tip ends of the ferrules 102 with optical fibres are polished.
  • US 5184433 discloses a method and apparatus of polishing the end of an optical fibre that produces relative lateral movement between the end of the fibre and an abrasive surface of the fibre in which the angle of attack of the relative movement is changed.
  • An object of the present invention is therefore to provide a method of polishing end surfaces of rod-shaped members in which the entire surface of a polishing sheet is uniformly used so that the lifetime of the polishing sheet can be elongated and running costs can be lowered.
  • Fig. 1 is a schematic structural view showing an embodiment mode of a polishing apparatus for practising the method of the present invention.
  • a polishing apparatus 1 is constructed as an apparatus for polishing the respective tip ends of a plurality of ferrules with optical fibres into spherical surfaces, and includes a circular polishing disc 2 and a holder (ferrule holder) 3 to be mounted by the ferrules with optical fibres.
  • the polishing disc 2 has a well known structure as shown in Fig. 2 in detail that a relatively thick elastic plate 22 having elasticity like rubber is disposed on a board 21 made of a stiff material, and a polishing sheet 23 is bonded to the elastic plate 22. As the polishing surface, even if an abradant is applied to the board 21 instead of the elastic material, the same result can be obtained.
  • the polishing disc 2 is attached to a driving apparatus (not shown).
  • a holder 3 formed as a long and narrow rectangular parallelopiped is fixed to a frame of the not shown driving apparatus by a suitable means so that the holder is aligned to be parallel with the polishing sheet 23 with a predetermined space therebetween.
  • the not shown driving apparatus is a motion causing apparatus of a well known structure capable of causing a trochoid curvilinear motion in a plane parallel with a main surface 2A of the polishing disc 2. As a result, the relative trochoid curvilinear motion can be given between the polishing disc 2 and the holder 3.
  • a plurality of ferrules 41 to 46 with optical fibres are mounted on a peripheral surface 3A of the holder 3 by well known means so that the ferrules have a predetermined posture to be almost vertical to the polishing disc 2.
  • the ferrules 41 to 46 with optical fibres are positioned so that the respective distances L1, L2, ... between the ferrules and the centre point C of the holder 3 are made different from one another (see Fig. 3)
  • the holder may be formed into any shape as long as a plurality of ferrules with optical fibres can be mounted thereon so that the distances between the respective ferrules and the centre of the polishing disc are different from one another. Accordingly, it is not necessarily required that the centre of the holder should coincide with the centre of the polishing disc. Further, in the example shown in Fig.
  • the method according to the present invention is not limited to this example, and the respective loci may partially overlap with one another as long as the distances between the respective rod-shaped members and the centre of the polishing disc are different from one another.
  • the rod shaped members could be arranged in groups having the same distance from the centre of the polishing disc with the distances of the respective groups being different such that although the loci of each group overlapped, the loci of different groups partially overlapped or did not overlap and almost all of the surface of the polishing sheet can be used.
  • the present invention since the distances between the respective rod-shaped members and the centre of a polishing disc are made different from one another, it is possible to avoid that only a specific portion of the polishing disc is concentrically used. As a result, it is possible to use almost all the surface of the polishing disc, so that the lifetime of the polishing disc can be elongated and the running costs can be decreased.
